How deep can flow analysis detect from the packet?



I have curiosity in relation to flow analysis. I read the document and it states that flow analysis identify only the header of the packet which contains the IP port, address and protocol. What more can it do as compared to Deep Packet Analysis, though it is a lower level analysis as compared to its counterpart. Can it also categorize the type of the packet, like separating the packet to streaming media,…etc.?


What Document?

What has this generic Topic have to do with the SAFE network?
